Back when I was young and ambitious I bought some KWM bushings from LaRose. Don't expect that I will ever need or use them. Here's a list of the KWM numbers: L? (all markings have rubbed of the plastic packet,), L33, L38, L39, L50, L51, L53, L82, L88, L89 KWM assortment 12000/V, and /VI All the KWM packages are marked with the dimensions of the bushing and which cutter to use for them and one mixed assortment LaRose stock number 049569 What are they worth? There are at least a dozen in each plastic bag. I paid $2.50 for each KWM plastic bag. And the 12000 assortments have as few as 2 bushings in a compartment and may be mixed up from the original since they are in plastic boxes with dividers for each size and the boxes have been turned over many times.
